Bug ID: 228432
Summary: [PATCH] sysctl `KERN_PROC_CWD` should return `ENOMEM`
when the output buffer isn't big enough
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---

patch fixing the issue
`man 3 sysctl` states: "If the amount of data available is greater than the
size of the buffer supplied, the call supplies as much data as fits in the
buffer provided and returns with the error code ENOMEM."
This is not true in the case of `KERN_PROC_CWD`, in which case `sysctl` returns
0, indicating success.
